Five Nights at Treasure Island is an unofficial Five Nights at Freddy's fan game inspired by the abandoned Disney Treasure Island urban legend. Its Nightmare Before Disney character, often shortened to NBD, became known for an especially harsh jumpscare compared with a standard FNAF jumpscare scream. Clips and rips of the sound circulated through YouTube horror edits, Scratch and Roblox fan games, and soundboards, where the brief duration made it easy to loop or trigger repeatedly. It remains popular because it delivers a complete scare in under two seconds.
